I've managed to run CPD[1] against harmony classlib. CPD (or cut/paste detector) is a tool that is capable of showing where code was cut/pasted from different parts of the source tree.
I managed to filter out all the tests (because they seem to have a good amount of cut/paste and that is not necessarily a problem) but there is still a lot of code that is was cut/pasted and might be worth considering for refactoring.
